Two days ago. Yes, that’s my own backyard. Yes, I’m in an N95. Why?

Both neighbours have COVID.

One side - Hacking lungs up outside and inside 24/7 for days on end. Other side - 26 weeks pregnant. Surrounded by COVID. Keeping CO2 low inside very carefully #aranet #maskoutside

#AlexKatz exhibit was super good, but if you go please bring an #N95. The #CO2 reached 2460 ppm. 2078 ppm at the foot of the ramp. I wonder if that’s normal or if they had the air on low? #Aranet #GuggenheimMuseum #nyc #covid #architecture

Very high CO2 reading on a very crowded C train yesterday at 3700 ppm. It might’ve even been the highest I recorded on the #Aranet, even higher than at the 911 museum at 2157 ppm which was also crowded.
